Toxic gasses escaping?  RSS feed

Hi all,
I am about to build my first rocket mass heater.

I am a little worried about toxic gasses escaping from the exhaust pipes or other parts.

Do I need to make sure that everything is sealed 100% before I add the layer of cob around everything, or will the layer of cob be enough to seal everything?

Joey J. : As man tries more and more to dominate his landscape he often turns to super chemicals that he barely understands the effects of
( or even doesn't and doesn't care !)

Since mans harnessing of fire ( with various levels of understanding, we have co-evolved around its use,for practical purposes we can say that
we recognize the burning eyes and stinging noses good clues that a heating unit is malfunctioning. We have survived and evolved with these
" Skills "

One of the most important parts of a good D.I.Y. Rocket build is an understanding of how our fire works in our rocket !

Carbon Monoxide IS a Dangerous gas needing only the opportunity to be concentrated in an enclosed place, or very long exposure times to
concentrate In Our Oxygen carrying Red blood cells !

Here is a good/bad place to mention cigarette smokers who are able to tolerate Elevated levels of Carbon Monoxide to get their 'Fix' -
nicotine!

Fortunately Carbon monoxide is a highly flammable gas and readily burns up -converts to carbon dioxide which again, if CO2 gets high in the
presence of fire/flame to cause a displacement of Oxygen (like a closed room ) will cause a poor burn and the production of those molecules
that burn our eyes and sting our nose !

Only by totally ignoring these warnings are we liable to get into trouble, and by that time your checked and functioning Smoke alarm will
have gone off ! To be safe, tape the smoke pipe joints and cover the pipe with clay slip to both seal and provide a surface to which the cob
will adhere tightly, any cracks in your final structural COB coat(s) can also be deal with with clay slip !

In haste big AL

Late Note ; Ernie W. describes a re-occuring event where the ''Monkey fingers'' of party goers play with the clean-out caps, and the parties
Host and Hostess find that their Rocket has a tendency to not ''Draft'' well, and some other problems, eventually tracing it down to a loose
Clean-out cap ! other than ''monkey fingers'' and yearly clean-outs this probably will not ever be a problem for you ! A.L.

Thanks, Your information put my mind at ease
 
When I was younger I felt like a man trapped inside a woman’s body. Then I was born. My twin is a tiny ad:
